FENCE-POST MOLD.

Specification of Letters Patent.

Patented Apr. 4:, 1911.

Application filed February 10, 1910. Serial No. 543,092.

To all whom it may concern.-

Be it known that I, Josnri-i H. GRAHAM, a citizen of the United States,residing at Kempton, in the county of Tipton and State of Indiana, haveinvented certain new and useful Improvements in Fence-Post Molds; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in molds for molding concretefence posts.

The primary object of this invention is to provide a simple andeconomical mold whereby a series of four or more posts may be molded ata single operation.

A further object of the invention is to provide a mold in which theparts may be readily separated after the concrete or other plasticmaterial from which the posts are made has hardened, and which may bereadily set up in molding or operative position.

With the foregoing and other objects in View, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a plan View of a moldembodying my improvements; Fig. 2 is a longitudinal section on the line2-2 of Fig. 1; Fig. 3 is an end view of the mold; Fig. 4 is a transversesectional view on the line 41 of Fig. 1; Fig. 5 is a detail elevationshowing the central clamping member detached; Fig. 6 is a detailperspective view of one of the end sections; Fig. 7 is a detailelevation of the contiguous end portion of the cooperating end member;Fig. 8 is a view of one end of the side members; and Fig. 9 is an edgeview of one of the clamping levers.

Referring to the drawings for a more particular description of theinvention, the mold comprises the side members 1 of steel or any othersuitable metal formed at their upper and lower side edges with theoutwardly bent reinforcing flanges 2, which add greater strength andrigidity to the side members.

The mold further comprises a series of "longitudinal spaced partitions3, which are suitably disposed between the side members to form themolds or compartments for the reception of the concrete or other plasticmaterial from which the molds are to be formed.

The mold further comprises the end sections or walls 1 and 5,respectively, each of which consists of a pair of slidably engagedsections, the longer, as (i, of which extends entirely across its end ofthe mold and is provided at one end with the inwardly and laterally bentportion 7, provided on its inner face with the cleat 8, which is adaptedto hook over a second cleat 9 on the adjacent end of one of the sidemembers and thereby form a means of interlocking engagementtherebetween. The shorter section of each end wall, as 10, is alsoprovided with the inwardly and laterally bent flange or portion 11,provided on its inner face with a cleat or rib 12, also adapted to hookover a second cleat 13 at the adjacent end of the other side member. Thelonger section 6 of each of the end walls is provided at one end and. atopposite sides with the guideways 14, which are preferably formed bysuitably bending the outer edges of metal strips 15 riveted or otherwiseattached to the face of said section. A locking lever 16 is pivoted nearone end upon a bolt 17 passing through a bearing bracket 18 mounted onthe outer face of the longer section of the end wall. The opposite orfree end of this lever is bent inwardly approximately at right angles toform a handle portion 19, which is adapted to be grasped by the operatorin moving the lever back and forth. The link 20 is loosely connected atone end to the locking lever 16 at a point adjacent the pivotal point ofthe latter and is connected at its opposite end by means of the bolt andbracket 21 and 22, respectively, with the shorter section of the endwall.

From the foregoing, it will be apparent that by swinging the operatinglever downward to the position indicated in Fig. 2,the sections of theend walls are drawn together and retain themselves, as well as the sidewalls, in molding position. .A series of pallets 23 are arranged in thebottoms of the mold compartments and rest upon the support upon whichthe mold as a whole is placed. The side walls, as well as thepartitions, are made of suflicient width to extend to the bottoms of thepallets. It will be observed that the side walls and partitions areshown of slightly and gradually decreasing width from one end of themold to the op- Cir posite end, while the partitions are so arrangedthat the mold compartments are also of slightly decreasing width and forthis reason, when the posts are formed, they will be larger at the basethan at their upper ends.

In order to hold the center of the mold from bulging down and to securegreater rigidity at this point, I provide a clamping member 24: whichextends across the bottom of the mold at the center of the length thereof and comprises a pair of corresponding sections 25 provided at theirouter ends with the hook portions 26 which receive the bottomreinforcing flanges 2 of the side walls of the mold, the ends of saidhook portions being bent up to form braces 27 which fit against theouter sides of the side members.

To adjust the sections of the clamping member 2a in locking or releasingposition, I provide the operating lever 28 which is pivoted near oneend, as at 29, to the inturned portion 30 of one of the sections 25 ofthe clamping member and is connected at the extreme portion of said endwith the other section of the clamping member. The outer end of thislever is provided with the handle 31 for convenience in operation. Eachof the end walls of the mold is also provided with the hook member 32which engages the upper edge of the central partition 3 to hold themachine from bulging up at the center. In setting up the mold, thepallets are first placed upon the support, the side walls next placed inposition and the center clamping member 24 next applied. The partitionsare then arranged in position between the pallets and the end walls orsections finally placed in position. The operating levers for the endwalls and center clamping member are then moved into locking position.To remove the machine from the posts, the end walls are first removedand next the center clamping member, which loosens the side walls. Theposts are now slightly separated by a suitable tool to facilitate theremoval of the partitions which are preferably removed endwise.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described I claim is 1. A mold of the character described,comprising longitudinal side members, a plurality of spaced longitudinalpartitions arranged between the same, sectional adjustable end members,eachcomprising a pair of slidably arranged clamping sections havingoppositely disposed inturned ends, guidmy invention, what ing meansextending from one of said sections, and clamping levers fulcrumed uponone of said sections and connected to the other section, whereby the endsections may be slidably adjusted upon each other.

, 2. A, mold of the character described, comprising longitudinal sidemembers, a plurality of spaced longitudinal partitions arranged betweenthe same, sectional adjustable end members, each comprising a pair ofslidably arranged clamping sections having oppositely disposed inturnedends, guiding means extending from one of said sections, clamping leversfulcrumed upon one of said sections and connected to the other section,whereby the end sections may be slidably adjusted upon each other, and adetachable central clamping means adapted to brace the side members,comprising a series of curved levers pivotally connected at their endsto an operating lever and having their outer ends bent upwardly andshaped to engage the lower portion of the side member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
